EFFECT OF CAFFEINATED AND DECAFFEINATED COFFEE ON BLOOD PRESSURE

Abstract

The world's most popular stimulant, caffeine, accounts for 80% of all caffeine consumption. It is widely used as a component in pharmaceuticals due to its high antioxidant and nutrient content, including phenol and polyphenol. On the presence of caffeine drinks are categorised as caffeinated and decaffeinated. The present study was conducted to evaluate the effect of caffeinated and decaffeinated coffee on blood pressure among the young generation. This experimental study was conducted on 85 healthy individuals (both male and female, non hypertensive) between 18-28 years of age. Blood Pressure (BP) was measured by an automatic digital blood pressure monitor, before and after taking of coffee in 30, 60, and 90 minutes. Each participant ingested 100 mL of coffee prepared from 50 mg of caffeinated coffee in water. The consumption time of each individual was between 2- 4 minutes. It was noticed almost 65.7% participants were found normal while, a significant difference in 34.3% found in systolic blood pressure (SBP) and diastolic blood pressure (DBP) after the intake of caffeinated coffee at p-value (<0.001).An increase of4.4 mmHg and 5.02 mmHg was found in systolic blood pressure after 60, 90 minutes respectively from the normal that is <20mm Hg. While, a slight increase was noticed in DBP after taking caffeinated coffee. No significant difference were seen after the congestion of decaffeinated coffee among participants. It was concluded by the study that individual responses can vary. There was increase in BP after taking caffeinated coffee. There was no significant effect found after decaffeinated coffee. Some people might be more sensitive to caffeine and feel its effects more strongly, while others might not notice much difference. Additionally, any effects from this small amount of coffee are likely to wear off relatively quickly, within a few hours at most.
